SpamAssassin should already have SPF checking capability. Check that you have the p5-Mail-SPF-Query port installed. Then check that there is a line: loadplugin Mail::SpamAssassin::Plugin::SPF in one of the files under /usr/local/etc/mail/spamassassin/ -- probably init.pre Note: this will not absolutely accept/reject mail based on SPF records alone. It will use SPF data to contribute to its spam scoring. Empirically it has been found that a matching SPF record is *not* a good predictor that a message is ham, but a non matching SPF record is a good predictor that a message is spam. (Or, in other words, some spammers are perfectly capable of setting up their own SPF records in the DNS) If you want to apply strict SPF checking, then the mail/sid-milter port is a pretty good choice.
